Insulation

Garage conversions will most likely need supplementary insulation as the garage space will be converted into a habitable room, and therefore must comply with building regulations for insulation in this kind of room. These regulations designate a U-value for insulation, which gauges the rate of heat loss. These are set differently for walls, flooring, and roofing. To meet building regulations the garage conversion must meet the U-values in all of the areas, but supplementary insulation can be installed to exceed these values and improve energy efficiency. Wall insulation for garage conversions is typically done by using internal wall insulation, which adds insulated plasterboard to the existing walls. This will add thermal insulation and stop heat from dissipating through the walls. Insulation must be added around doors and windows as these areas can leak heat particularly badly. Roofs for garage conversions will also require insulation. Pitched roofs need insulation to the same level as the rest of your house. Flat roofs also require insulation. This is done utilizing a cold roof system, where insulation is fixed between the roof joists along with ventilation to avoid condensation forming. The other possibility is a warm roof, where insulation is added above the roof joists. Floor insulation is also needed in garage conversions. This is easier if the floor level of the garage requires elevating in order to meet the rest of the house as an extra layer of insulation can be easily added to either a lifted concrete floor, timber joists or a floating floor. If the floor does not need to be raised it may be necessary to dig out the floor to add the necessary insulation.
